摘要： A method of providing an input signal to a mixer circuit comprises coupling an output signal from a low-noise amplifier circuit to a mixer input of the mixer circuit via an AC coupling circuit, comprising an inductive of capacitive coupling circuit. For capacitive coupling configurations, a coupling capacitor is configured to have a capacitance value determined as a function of a transconductance sensitivity of the mixer circuit. For balanced output configurations of the low-noise amplifier circuit, matched coupling capacitors are used for coupling the balanced output signals to respective inputs of the mixer circuit. In one embodiment, the mixer circuit comprises a quadrature mixer circuit, which may be in a balanced or double-balanced configuration. In another embodiment, the mixer circuit comprises a four-phase mixer circuit, which may be configured as a balanced four-phase mixer circuit coupled to the low-noise amplifier circuit via inductive or capacitive embodiments of the coupling circuit.

摘要： A variable integrated inductor is described herein which has an inductance value that can be switched between two or more values. In the preferred embodiment, the variable integrated inductor includes a multi-loop primary inductor which is electromagnetically coupled to a pair of secondary inductors. The secondary inductors are connected to one another to form a closed circuit within which the secondary inductors have a changeable topology that can be switched between a series connection and a parallel connection in order to change an inductance value which is output by the multi-loop primary inductor. In one application, the variable integrated inductor is used in a voltage controlled oscillator (VCO) which is of the type that can be used in a multi-band RF radio transceiver (e.g., wireless communication device). In other applications, the variable integrated inductor can be used in a tuned amplifier load, an impedance matching network, a digitally controlled oscillator or any other type of frequency selective LC-network.

摘要： The present invention relates to a method for tuning a radio filter. The filter comprises an input connection, an output connection and at least two resonator modules coupled in cascade, each having a tuning mechanism and a probe. A first resonator module is connected to the input connection and a final resonator module is connected to the output connection. The filter is adapted to receive at least one signal within a frequency range. The method comprises essentially two steps: coarse tuning, which is dependent on the frequency content of the received signal(s), and fine tuning, which is dependent on a calculated deviation between a set value vector and a measured signal parameter vector. A relationship between the set value vector and the signal parameter vector is established for calculating the deviation. The invention also relates to a radio filter and a system comprising such a radio filter.

摘要： Method and system are disclosed for reducing mutual EM coupling between VCO resonators and for implementing the same on a single semiconductor chip. The method and system involve using inductors that are substantially symmetrical about their horizontal and/or their vertical axes and providing current to the inductors in a way so that the resulting magnetic field components tend to cancel each other by virtue of the symmetry. In addition, two such inductors may be placed near each other and oriented in a way so that the induced current in the second inductor due to the magnetic field originating from first inductor is significantly reduced. The inductors may be 8-shaped, four-leaf clover-shaped, single-turn, multi-turn, rotated relative to one another, and/or vertically offset relative to one another. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
